Sony is making a change to its usage policies for PlayStation Network on November 18 that will limit PSN content to only two devices. As of that Friday, PS3 and PSP users will only be able to play their games on up to two activated systems, down from five. This policy will only be used for game content (as opposed to game and video content) purchased after November 18.
Sony is also planning to provide a new PSN account management website where users will be able to "deactivate particular devices attached to their PlayStation Network account via their PC." So if you have had a dead PS3 or PSP for a while you'll be able to deactivate via the website rather than sending the device back to Sony to do it for you.
There are a lot of angry PSN users commenting about the policy change on the PlayStation blog. Personally I only have one PS3 so I don't intend to be affected by this change, but for those with multiple devices they seem to think this is a huge deal. Will this policy change affect you, and what do you think of Sony's decision to reduce the number of activated systems that you can have?
